A hidden leak can quietly waste thousands of gallons and damage your home before you ever see a drop. Our team provides fast, accurate leak detection in San Diego using non-invasive electronic, acoustic, and thermal-imaging tools — so we find the exact source without tearing up your floors or walls.
Whether it's a slab leak under your foundation, a supply line behind drywall, or a gas line you can smell but can't see, Tri Express Plumbing pinpoints the problem and explains your options with upfront pricing. We've handled leak detection across San Diego County since 2008. Repair work is backed by our 1-year workmanship warranty, and whole-house repipes carry a 25-year warranty.
Caught a leak that's already done damage? After detection we can move straight into repair, a whole-home repipe, or a partial reroute. Need other plumbing too? We also handle water heater installation and ADU plumbing across the county.
Full-service detection for every kind of hidden leak in your home.
Electronic and acoustic location of leaks under your concrete foundation — pinpointed before any cutting begins.
Hidden water leaks in supply lines, walls, ceilings, and under floors located with pressure testing and listening equipment.
Safe location of natural gas leaks with proper testing — then a code-compliant repair once the line is secure.
Camera inspection and locating to find cracked or leaking sewer and drain lines beneath the property.
We review symptoms — high bills, wet spots, low pressure — and isolate the affected system.
Electronic, acoustic, and thermal tools locate the exact leak with no demolition.
You get a clear diagnosis and upfront repair options before any work starts.

Here's the truth most plumbers won't tell you: insurance does not pay for the plumbing repair itself — fixing the pipe is on you. What a covered policy typically does pay for is the leak detection, the access work to reach the leak, and the resulting water damage — drywall, flooring, and the like. And that coverage only holds when the leak is sudden and accidental. If your carrier determines the leak was ongoing or long-term, the claim is typically denied, and once mold is present, a denial is almost certain. That's why speed matters: the sooner a leak is found and documented, the stronger your position. We locate and document the leak the same day so you have accurate findings to submit. Always confirm specifics with your carrier.
See Our Insurance Claim ReportsMost plumbers have never seen a denial letter. We have. After more than 15 years working alongside restoration companies and insurance carriers across San Diego County, we know exactly what gets a water-damage claim paid — and what gets it denied. Sudden, documented leaks found early stand the best chance. Leaks that sat for months, or that led to mold, almost never do. We bring that claims-side experience to every San Diego inspection: finding the leak fast, documenting it correctly, and giving you a straight answer about where you stand — not marketing promises we can't keep.
Fast response across San Diego County — we can locate most leaks the same day you call.
